Hi matwhite,
Thank you for using the Support Forum. From the Compatability matrix for the Mac 10.8 and 10.9 drivers it states that:
"Scan Driver Compatibility with Mac OS X 10.8
Some scan functionality is diminished in Mac OS X 10.8. In particular, scanning via the SMB protocol is no longer supported due to architectural changes in Mac OS X 10.8. Please continue to visit Xerox.com/drivers periodically for updates regarding enhancements to scan drivers that address this change."
This compatibility issue is the same in the Mac OS X 10.9. Please consider contacting your support centre for further assistance.
